It works on iP 4 and 5. For iphone 4 i made a plist defining 5 rows and for iPhone 5 a plist with 6 rows, you´ll have it soon: No gap, no dock, page dots at bottom, pressing icons and scrolling on the whole screen. Build in by default with exxOS beta 2

I´m just running last tests on iP 4 and must theme the iOS 6 iPhone 4/s camera.
Unfortunately there are some apps that have to be themed three times (like cam or dialer: for iOS 5, iOS 6 and again for iPhone 5)
